CVE-2026-54640 Details
Description
OpenRemote is an open-source internet-of-things platform. Prior to 1.24.2, the KNXProtocol.startAssetImport method in agent/src/main/java/org/openremote/agent/protocol/knx/KNXProtocol.java processes 0.xml from an authenticated user's uploaded ETS project ZIP with Saxon TransformerFactoryImpl and XMLInputFactory parsers that permit external entity resolution. This incomplete remediation of CVE-2026-40882 leaves the KNX handler unprotected while the parallel Velbus handler is hardened, allowing a regular realm user to read files accessible to the JVM process or cause server-side requests. This issue is fixed in version 1.24.2.
A vulnerability allowing XML External Entity (XXE) injection has been identified in the OpenRemote IoT platform, specifically in the KNXProtocol asset import handler. This issue, present in versions through 1.24.1, arises because the 'startAssetImport' method processes user-uploaded ETS project ZIP files without proper security measures against external entity resolution. As a result, authenticated users can exploit this vulnerability to read arbitrary files from the server's filesystem or initiate server-side requests. The vulnerability stems from an incomplete remediation of a previous XXE-related issue, leaving the KNX handler unprotected while other handlers have been fortified.
Users can update to OpenRemote version 1.24.2, which addresses this vulnerability by implementing proper XXE protections in the KNXProtocol asset import handler.
